This update corrects a problem in CCF period calculation (for periodically tested component).
The old method was too concervative, it is now solved.
You have to apply this update if you use boolean modules (Tree, SIL …)

Moreover, it corrects a bug in 64-bit version. it was always in demo mode.
For every 64-bit operating system user, we recommand you to use this version.

This new version corrects/adds :
– Petri12: Filters on place-name are now available in results
– BFiab: It increases performances for Reliability Bloc Diagram with more than 1000 Blocs
– Petro: Calculation improvment for the contribution to losses
– Petro: Start-up time taken into account for every restart (and not only the first)
– SIL: PieChart Always visible in PDF report
– SIL: correct component information displayed in PDF report when “Existing component” is used
– SIL: many small corrections (SIF order in report, Solveur with “Existing component”, …)
– Tree : Logical-Tree-View corrected

Corrections :
– Tree, BFiab: Prime impliquants display corrected (negations were misplaced),
– Tree: Objectives calculus corrected as they are restrictive in the case of repeated events
– Petri12: Display under transitions: ? and ! simple to respect the IEC 62551
– Petri12: Time unit and calculus type memorization within specific variable configuration
– GRIF: The « Search for shortcuts » function applies to an object on the current page displayed only
– Albizia: Updated to version 0.4e

Enhancements :
– SIL: Wrong reconfiguration probability has been slip up in 2 Omega: after test Omega and after repair Omega
– BStoK: Possibility to make batches modifying the resources (spare parts, maintenance teams)
– ETree: Template and example added in order to ease the module first handling

a new version of GRIF-Workshop is now available. This version brings a great number of evolutions for all the modules, the main upgrades are:

GRIF (all modules)
– A new Copy/Paste allows you to choose the way the data are renamed (Use of suffix, prefix or search/replace),
– Rectangle tool added and possibility to anchor it for zones definition,
– Automatic batch creation by parameter variation,
– Possibility to save documents as templates,
– Excel format export of the results,
– Open files directly in Windows explorer,
– Possibility to display a computation report in a dynamic field,
– Copy/Paste of data tables from/to a spreadsheet,
– Automatic input of data access scripts in dynamic fields.

Curves (Improved chart system available for all modules)
– Possibility to add several curves all at one time in chart zone,
– Curves composed of dots generated by different computations,
– Size and unit management on the abscissa and ordinate,
– Display of pie charts/histograms depending on the time spent inside the zones.

Tree (Boolean package)
– Possibility to specify a probability objective on a gate and do probability allocation,
– Possibility to choose the doors and events sizes,
– Open-PSA format export,
– Empirical law added to be able to use computations generated by other computation engines (Markov …).

Boolean computation (Upgrade available for all Boolean modules)
– Possibility to configure, under each object, the results to be displayed,
– Results column added (configurable) in the data table,
– UFI and MIF computations management on the non-coherent trees,
– A new type of data “component” has been added, it is made of several failure modes, ans you can compute minimal cut sets taking into account the “full component failure” and not each failure mode.
– Concept of “initiator events” that allows to define the appearance order of events for the frequency computation.

Booléenmodule (new module of boolean package)
– The Boolean module is now fully operational. It allows the use of various modeling types (Fault Tree, Block Diagram, Event Tree, Safety Loop) within the same document and the interaction between different parts.

ETree
-The 2012 version of the ETree module was limited to simple frequency computations, the 2013 version has all the required functions to elaborate a risk study considering:

The consequence gravity of each scenario,

The risks matrix with the acceptability zones.

Petri12 (package Simulation)
– Possibility to display seed that are used during simulation (for each story),
– You can know duplicate several data simultaneously (variables/parameters/tables),
– Multiprocessor computation up to 12 CPU,
– New result for place : number of token at the end of history
– Interactive simulation : automatic progress until a transition firing,
– Engine performance statistics added (to estimate computation time),
– Data “call hierachy” to identify where the variables/parameters/places are used…

Dear GRIF-workshop users,
GRIF 2012.3 is available, it is an update of 2012 version, it contains the following corrections :
– it uses the number format defined in document-options when a number is displayed in dynamic fields
– it corrects some bugs in Petri12 module and adds a new version of Moca-RP (13.12)
– it adds warning when you incorrectly use time() operator in Petri12
– it corrects bugs when you opens documents from 2011-SP1 version containing batch computations (every module but SIL).

For SIL module
– Many loops in a document
– Third Beta level (for sub-actuators)
– 1oo2 or 2oo2 sub-actuators
– specific part configuration (not only KooN)
– simple architecture modification with right-click on the system view
– new report layout with synthesis
